How can I make the service add 1 word per page every minute?

Question

PHP

Hi all. There is a completely blank page, how to make it add 1 random word from the list every minute? Service time from a week, with page cleaning after a certain number of words.
There is no cron on the hosting.

Answer 1

In this case, words with a period of 3 seconds

<?

$period = 3;

if (file_exists("last_time")) {
  $last_time = @file_get_contents("last_time");
  $current_time = time();
} else {
  $current_time = time();
  $last_time = $current_time-$period;
}

$steps = floor(($current_time - $last_time) / $period);

if ($steps > 0) {
  $words_list = array("слово 1", "слово 2", "слово 3", "слово 4", "слово 5", "слово 6", "слово 7", "слово 8");

  $words_add = array();
  for ($i = 0; $i < $steps; $i++) {
    $words_add[] = $words_list[rand(0, count($words_list)-1)];
  }
  
  $f = fopen("words", "a+");
  fwrite($f, implode("<br>", $words_add) . "<br>");
  fclose($f);

  file_put_contents("last_time", $current_time);
}

echo @file_get_contents("words");
?>

<script>
  setTimeout(function () {document.location.reload(); }, 3000);
</script>

Answer 2

refresh the page once per second. Use java script.

There is no cron on the hosting.
There can be no cron on the hosting. Another thing is that there may not be access to its management :)
